In order to obtain the desired mechanical properties of connecting bar after quenching and tempering, and reduce the cracking
tendency and distortion, a program of controllable quenching was established. Furthermore, a computer-aided quenching (CAQ)
system was developed. The applications show satisfactory results. 相似文献
